TECHNICAL FIELD

The present invention relates to service providing systems, information processing apparatuses, information processing methods, and programs. More particularly, the present invention relates a service providing system, an information processing apparatus, an information processing method, and a program, which are capable of reducing leakage of the private information of a user.

BACKGROUND ART

A system that provides useful information to a user transmits article information and sale information of a shop by wireless to a distribution area within a predetermined distance from the information terminal of the shop and, when the user who carries a mobile terminal enters the distribution area, automatically receives the article information and the sale information to store the received information. The system has separate means for searching the information by a consumer (for example, refer to Japanese Unexamined Patent Application Publication No. 2000-276532 (pages 5 to 7)). A system registers an article desired by a user in advance and raises an alarm when a shop has the article desired by the user (also refer to Japanese Unexamined Patent Application Publication No. 2000-276532 (pages 5 to 7)).

A system presents advertisement information to be presented to an driver of a mobile body in a form of at least one of an image and a sound, depending on the situation of the mobile body, in order to allow the driver of the mobile body, who wants to use the advertisement information, to watch and listen to the advertisement information in a more secure situation. The system uses a global positioning system (GPS) to determine the position of the mobile body and presents the advertisement information of a shop when the mobile body reaches an area within a distance of, for example, 2 km from the shop (for example, refer to Japanese Unexamined Patent Application Publication No. 2000-292182 (pages 4 to 5)).

In a system having elements and nodes, which constitute the system, connected thereto over a network, a cyber-entity (hereinafter referred to as a CE), which is a program executed by the nodes, acquires information input by a user; history information of the user; real world information (information concerning the user, such as the position of the user or the biological information, the concentration of nitrogen gas in the air, humidity, opening/closing of a door, the water level of a pot, turning on/off of an electric lamp, wind speed, water depth, electric conductivity, luminance, odor, a traffic situation, the freshness of food, room temperature, and/or precipitation) acquired by using a sensor; attribute information of the CE; and so on (environmental sensing), and acquires information concerning other CEs (B) by the environmental sensing. The CE generates and records relationship information of the CEs (B) based on the acquired information concerning the CEs (B), and selects a target CE to be interacted with based on the relationship information to provide a service while interacting with the target CE (for example, refer to Japanese Unexamined Patent Application Publication No. 2002-175405 (pages 9 to 11)).

A system stores the characteristics of a shop where a base terminal computer is installed in the base terminal computer as base terminal device profile. In this system, when the mobile terminal computer of a user is connected to the base terminal computer, the user profile is transmitted to the terminal device computer and is updated so as to reflect the base terminal device profile of the base terminal computer in order to reflect the preference of the user in the user profile and to be accommodated to the user's interest that dynamically varies (for example, refer to Japanese Unexamined Patent Application Publication No. 2002-117066 (pages 12 to 13)).

However, with known systems, there is a problem in that the private information of a user must be provided to the outside when the information suited to the preference of the user is recommended to the user.

For example, in the system disclosed in the Japanese Unexamined Patent Application Publication No. 2002-117066 (pages 12 to 13), the user profile must be transmitted from the mobile terminal computer to the base terminal computer.

Accordingly, the transmission can result in leakage of the private information of the user.

BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 shows an example of the structure of a service providing system of the present invention. Although a case in which article information of articles sold in a shop is provided to a user is described in the following description, this does not mean that the present invention is limited to the provision of the article information. That is, profitable information which the service providing system of the present invention provides to the user may be information other than the article information.

In the service providing system in FIG. 1, an access point 4, a shop-information portal site server 5, a stock management server 6, and a positional information service server 7 are connected to a network 1 including the Internet. An information processing apparatus 2 performs wireless communication over a wireless local area network (LAN) with the access point 4 and is connected to the network 1 through the access point 4. An information processing apparatus 3 performs communication with the information processing apparatus 2 using a Bluetooth technology. The information processing apparatus 3 may communicate with the information processing apparatus 2 over the wireless LAN.

The shop-information portal site server 5 provides article information of articles sold in shops (for example, the names, sizes, colors, prices, and/or characteristics of the articles) and others over the network 1. The shop-information portal site server 5 has at least one shop registered therein and provides the article information sold in the registered shop over the network 1.

The stock management server 6 manages stock information of the articles that are sold in the shops registered in the shop-information portal site server 5. The positional information service server 7 associates objects (for example, shops, companies, parks, and rivers) located at predetermined longitudes and latitudes on a map with the corresponding longitudes and the latitudes and stores the associated objects. When the information concerning a longitude and latitude is specified, the positional information service server 7 determines an object located at the specified longitude and latitude. When the positional information service server 7 receives the longitude and latitude of the current position of the user and the longitude and latitude of a destination, the positional information service server 7 determines the route from the current position of the user to the destination, generates routing information used for guiding the user to the destination, and transmits the generated routing information to the information processing apparatus (base unit) 2. The base unit 2 may have the information in the positional information service server 7 and may generate the routing information instead of the positional information service server 7.

The user receiving a service from the service providing system of the present invention carries the information processing apparatus 2 and the information processing apparatus 3 as one set. The information processing apparatus 2 is hereinafter also referred to as the base unit 2. The information processing apparatus 3 is hereinafter also referred to as a remote unit 3. The remote unit 3, which has a sensor for acquiring multiple different pieces of information, acquires the information concerning the user through the sensor and transmits the acquired information to the base unit 2. The remote unit 3 also has a function as electronic money. When the user pays the price using the remote unit 3, the remote unit 3 transmits, to the base unit 2, purchase information including the name, price, and purchase date and time of an article purchased by the user.

The base unit 2 acquires, from the positional information service server 7, the information concerning an object (for example, a shop, a company, a park, or a river) located at the current position of the user. When the user is located at, for example, a shop, or when the user is located near the shop, the base unit 2 acquires the article information of the articles sold in the shop from the shop-information portal site server 5 over the network. In addition, the base unit 2 acquires the information concerning the user and the purchase information from the remote unit 3. The base unit 2 selects an article according to the user preference based on the article information supplied from the shop-information portal site server 5, the information concerning the user, supplied from the remote unit 3, and the purchase information, transmits the article information of the selected article to the remote unit 3, and causes the user to recommend the selected article.

Furthermore, the base unit 2 notifies the positional information service server 7 of the longitude and latitude of the current position of the user and the destination, and acquires the routing information used for guiding the user to the destination from the positional information service server 7. The base unit 2 then causes the remote unit 3 to present the acquired routing information. As described above, the base unit 2 may have the information in the positional information service server 7 and may generate the routing information instead of the positional information service server 7.

The remote unit 3 is removable from the base unit 2. FIGS. 2 and 3 illustrate how the remote unit 3 is removed from the base unit 2.

The components having the same name have the same functions. Accordingly, a description of the components is omitted here.

The summary of the service providing system of the present invention will now be described with reference to the flowchart in FIG. 13. FIG. 13 shows a service providing process in the service providing system of the present invention.

Referring FIG. 13, in Step S101, the CPU 151 in the remote unit 3 acquires information supplied from the sensors including the microphone 102, the heartbeat detecting unit 157, the temperature-humidity sensor 103, the GPS detecting unit 125, the imaging unit 121, the triaxial motion sensor 128, and the magnetic sensor 127 or purchase information of an article, when payment is performed through the IC communication unit 104. The information supplied from the sensors and the purchase information are hereinafter also collectively referred to as user information.

In Step S102, the CPU 151 in the remote unit 3 transmits the user information acquired in Step S101 to the base unit 2 through the Bluetooth communication unit 126.

In Step S121, the CPU 201 in the base unit 2 receives the user information transmitted by the remote unit 3 in Step S102 through the Bluetooth communication unit 221 and stores the received user information in the HDD 223.

The shop-information portal site server 5 stores a database including the information concerning the articles sold in the shop in the HDD 304. In Step S131, the CPU 301 in the shop-information portal site server 5 transmits the information stored in the database (hereinafter also referred to as database information) to the base unit 2 through the communication unit 311.

In Step S122, the CPU 201 in the base unit 2 receives the database information transmitted by the shop-information portal site server 5 in Step S131 through the wireless LAN communication unit 225 and stores the received database information in the HDD 223.

In Step S123, the CPU 201 in the base unit 2 performs data mining based on the user information received and stored in Step S121 and the database information received and stored in Step S122 to select information anticipated being useful to the user. The CPU 201 then generates information to be recommended to the user (the information recommended to the user is hereinafter also referred to as recommendation information) based on the selected information. An existing method, such as a genetic algorithm or AI, is used in the data mining.

Learning in the operation history (or the sensing history) of the user with the remote unit 3, the purchase of articles, and the operation history, such as Web browsing, of the user with the base unit 2 in the data mining can draw inference better suited to the preference or interesting of the user. The data mining based on the operation history of the user may be performed at a timing other than the timing when the user information is received from the remote unit 3 (Step S123). For example, the operation history of the user may be accumulated in advance for a predetermined time for the learning in the data mining.

In Step S124, the CPU 201 in the base unit 2 requests, through the Bluetooth communication unit 221, the remote unit 3 to recommend the recommendation information generated in Step S123.

In Step S103, the CPU 151 in the remote unit 3 receives the request for the recommendation of the recommendation information from the base unit 2 through the Bluetooth communication unit 126. In Step S104, the CPU 151 in the remote unit 3 presents the information to the user in response to the request received in Step S103.

The service providing process is performed in the manner described above.

The user information is supplied from the remote unit 3 to the base unit 2 in Step S101, Step S102, and Step S121 in FIG. 13. Specifically, the processing in these steps is performed according to, for example, a flowchart shown in FIG. 14 or FIG. 15.

An example of the process of supplying the user information from the remote unit 3 to the base unit 2 will now be described with reference to the flowchart in FIG. 14. In Step S161, the CPU 201 in the base unit 2 requests the user information from the remote unit 3 through the Bluetooth communication unit 221. The user information requested in Step S161 may be any of, for example, the audio information acquired by the microphone 102, the heart rate of the user calculated by the heartbeat detecting unit 157, the temperature and humidity detected by the temperature-humidity sensor 103, the longitude and latitude measured by the GPS detecting unit 125, the object an image of which is picked up by the imaging unit 121, the three-dimensional attitude angle detected by the triaxial motion sensor 128, and the information detected by the magnetic sensor 127 or may be any combination of the above information. Or, all of the above information may be detected here.

In Step S151, the CPU 151 in the remote unit 3 receives the request for the user information from the base unit 2 through the Bluetooth communication unit 126. In Step S152, the CPU 151 in the remote unit 3 acquires the user information supplied from the sensors including the microphone 102, the heartbeat detecting unit 157, the temperature-humidity sensor 103, the GPS detecting unit 125, the imaging unit 121, the triaxial motion sensor 128, and the magnetic sensor 127. The information acquired by the CPU 151 in Step S152 is the information requested by the base unit 2 in Step S161. In other words, the CPU 151 does not necessarily acquire the information from all of the microphone 102, the heartbeat detecting unit 157, the temperature-humidity sensor 103, the GPS detecting unit 125, the imaging unit 121, the triaxial motion sensor 128, and the magnetic sensor 127 but acquires only the information requested by the base unit 2. For example, when the information concerning the temperature is requested by the base unit 2, the CPU 151 acquires only the information concerning the temperature from the temperature-humidity sensor 103.

In Step S153, the CPU 151 transmits the user information acquired in Step S152 to the base unit 2 through the Bluetooth communication unit 126.

In Step S162, the CPU 201 in the base unit 2 receives the user information transmitted by the remote unit 3 in Step S153 through the Bluetooth communication unit 221. In Step S163, the CPU 201 in the base unit 2 stores the user information received in Step S162 in the HDD 223.

The user information is supplied from the remote unit 3 to the base unit 2 in the manner described above. As described above, the remote unit 3 can acquire the user information requested by the base unit 2 and supply the acquired user information to the base unit 2.

An example, different from the one shown in FIG. 14, of the process of supplying the user information from the remote unit 3 to the base unit 2 will now be described with reference to the flowchart in FIG. 15.

In the example in FIG. 15, the timing of acquisition of the user information is set in advance in the remote unit 3. In Step S181, the CPU 151 in the remote unit 3 determines whether it is time to acquire the user information. The CPU 151 repeats the processing in Step S181 and is on standby until the CPU 151 determines that it is time to acquire the user information.

For example, the remote unit 3 can be set in advance so as to transmit the temperature information to the base unit 2 every minute. With this setting, the CPU 151 in the remote unit 3 determines whether it is time to acquire the user information (temperature information) every minute in Step S181.

If the CPU 151 determines that it is time to acquire the user information in Step S181, the process proceeds to Step S182. In Step S182, the CPU 151 in the remote unit 3 acquires the user information determined to be acquired in Step S181.

Since the processing in Step S183 is the same as that in Step S153 in FIG. 14, a description is omitted here. In addition, since the processing in the base unit 2 in Step S191 and Step S192 is the same as that in Step S162 and Step S163 in FIG. 14, respectively, a description is omitted here.

As described with reference to the flowchart in FIG. 15, the remote unit 3 may automatically acquire the user information at a predetermined timing that is set in advance and supply the user information to the base unit 2.

The database information is supplied from the shop-information portal site server 5 to the base unit 2 in Step S131 and Step S122 in FIG. 13. Specifically, the processing in these steps is performed according to, for example, a flowchart shown in FIG. 16 or FIG. 17.

An example of the process of supplying the database information from the shop-information portal site server 5 to the base unit 2 will now be described with reference to the flowchart in FIG. 16. In Step S201, the CPU 201 in the base unit 2 requests the database information from the shop-information portal site server 5 through the wireless LAN communication unit 225. The database information requested in Step S201 is, for example, information concerning the price, size, or color of an article sold in the shop.

In Step S211, the CPU 301 in the shop-information portal site server 5 receives the request for the database information from the base unit 2 through the communication unit 311. In Step S212, the CPU 301 in the shop-information portal site server 5 reads out the database information from the HDD 304 and transmits the readout database information to the base unit 2 through the communication unit 311.

In Step S202, the CPU 201 in the base unit 2 receives the user information transmitted by the shop-information portal site server 5 in Step S212 through the wireless LAN communication unit 225. In Step S203, the CPU 201 in the base unit 2 stores the database information received in Step S202 in the HDD 223.

The database information is supplied from the shop-information portal site server 5 to the base unit 2 in the manner described above. As described above, the shop-information portal site server 5 can supply the database information requested by the base unit 2 to the base unit 2.

An example, different from the one shown in FIG. 16, of the process of supplying the database information from the shop-information portal site server 5 to the base unit 2 will now be described with reference to the flowchart in FIG. 17.

In the example in FIG. 17, the timing of supply of the database information to the base unit 2 is set in advance in the shop-information portal site server 5. In Step S241, the CPU 301 in the shop-information portal site server 5 determines whether it is time to transmit the database information. The CPU 301 repeats the processing in Step S241 and is on standby until the CPU 301 determines that it is time to transmit the database information.

For example, the shop-information portal site server 5 can be set in advance so as to transmit the information concerning daily bargains to the base unit 2 every day. With this setting, the CPU 301 in the shop-information portal site server 5 determines whether it is time to acquire the database information every day in Step S241.

If the CPU 301 determines that it is time to acquire the database information in Step S241, the process proceeds to Step S242. In Step S242, the CPU 301 in the shop-information portal site server 5 reads out the database information from the HDD 304 and transmits the readout database information to the base unit 2 through the communication unit 311.

Since the processing in the base unit 2 in Step S231 and Step S232 is the same as that in Step S202 and Step S203 in FIG. 16, respectively, a description is omitted here.

As described with reference to the flowchart in FIG. 17, the shop-information portal site server 5 may automatically transmit the database information to the base unit 2 at a predetermined timing that is set in advance.

In Step S123, the base unit 2 selects information anticipated being useful to the user based on the user information and the database information acquired in the manner described above. In Step S124, the base unit 2 requests the remote unit 3 to recommend the information selected in Step S123.

Conventionally, the processing performed by the base unit 2 in Step S123 has been performed by a server provided on the network 1. In such a case, it is necessary to transmit the private information of the user to the server over the network 1. In contrast, storing and managing the user information in the base unit 2 owned by the user, as in the service providing system of the present invention, prevents the user information from being transmitted to the server on the network 1, thus reducing the possibility of leakage of the private information of the user.

Examples in which the service providing system of the present invention is applied to specific situations will be described below.

First, a process of recommending an article to the user based on positional information will now be described with reference to the flowcharts in FIGS. 18 to 27. FIG. 18 shows a process of transmitting GPS information in the remote unit 3. FIGS. 19 and 20 show a process of recommending an article based on the positional information in the base unit 2. FIG. 21 shows a process of providing the positional information in the positional information service server 7. FIG. 22 shows a process of providing article information in the shop-information portal site server 5. FIG. 23 shows a process of providing stock information in the stock management server 6. FIG. 24 shows a process of presenting information in the remote unit 3. FIG. 25 shows a process of confirming recommendation in the remote unit 3. FIG. 26 shows a process of providing routing information in the positional information service server 7. FIG. 27 shows a route guiding process in the remote unit 3.

For example, the remote unit 3 is set in advance so as to acquire the GPS information for every ten minutes. When it is time to acquire the GPS information, the remote unit 3 performs the process of transmitting the GPS information shown in FIG. 18. Referring to FIG. 18, in Step 301, the CPU 151 in the remote unit 3 acquires the GPS information through the GPS detecting unit 125. In Step S302, the CPU 151 in the remote unit 3 transmits the GPS information to the base unit 2 through the Bluetooth communication unit 126.

The base unit 2 starts the process of recommending an article based on the positional information, shown in FIG. 19. Referring to FIG. 19, in Step S321, the CPU 201 in the base unit 2 receives the GPS information transmitted by the remote unit 3 in Step S302 through the Bluetooth communication unit 221 and stores the received GPS information in the HDD 223. In Step S322, the CPU 201 in the base unit 2 transmits the GPS information to the positional information service server 7 through the wireless LAN communication unit 225 and requests information concerning a building, a shop, a facility, or the like, located at the location corresponding to the GPS information (the longitude and latitude) (the information concerning a building, a shop, a facility, or the like, located at the location corresponding to the GPS information, is hereinafter also referred to as the positional information).

The positional information service server 7 performs the process of providing the positional information, shown in FIG. 21. Referring to FIG. 21, in Step S361, the CPU 401 in the positional information service server 7 receives the request for transmission of the GPS information and the positional information, transmitted by the base unit 2 in Step S322. In Step S362, the CPU 401 in the positional information service server 7 reads out the positional information corresponding to the GPS information received in Step S361 from the HDD 404 and transmits the read out positional information to the base unit 2 through the communication unit 411.

Referring back to FIG. 19, in Step S323, the CPU 201 in the base unit 2 receives the positional information transmitted by the positional information service server 7 in Step S362 through the wireless LAN communication unit 225. In Step S324, the CPU 201 in the base unit 2 determines whether the user is located in the shop based on the positional information. If the user is not located in the shop, the process goes back to Step S321 and repeats the steps subsequent to Step S321.

If the CPU 201 determines in Step S324 that the user is located in the shop, the process proceeds to Step S325. Although the base unit 2 determines only whether the user is located at the shop at the present moment in Step S324 in the above description, the base unit 2 may determine that the user is located in the shop, for example, when the user is located in the same shop for a time period longer than a predetermined time period that is set in advance and, then, the process may proceed to Step S325.

In other words, the base unit 2 periodically may acquire the GPS information from the remote unit 3 and may determine whether the user is located in the same shop for a predetermined time period based on the GPS information. If the user is located in the same shop for a time period longer than the predetermined time period that is set in advance, the base unit 2 determines that the user is located in the shop and the process proceeds to Step S325.

Although the case in which the user is located in the shop is described above, the base unit 2 may determine whether the user is located near the shop.

The HDD 223 in the base unit 2 stores the history of articles which the user has purchased (the history of the articles which the user has purchased is hereinafter referred to as shopping history). In Step S325, the CPU 201 in the base unit 2 determines a preference of the user based on the shopping history. The determination is performed based on an existing data mining method. For example, a manufacturer or brand of cosmetics which the user frequently purchases or a color according to user preference is determined in Step S325.

In Step S326, the CPU 201 in the base unit 2 requests information concerning the articles sold in the shop where the user is currently located (the information concerning the articles sold in a shop is hereinafter referred to as article information) from the shop-information portal site server 5 through the wireless LAN communication unit 225.

The shop-information portal site server 5 starts the process of providing the information concerning the article shown in FIG. 22. Referring to FIG. 22, in Step S381, the CPU 301 in the shop-information portal site server 5 receives the request for the article information transmitted by the CPU 201 in the base unit 2 in Step S326 through the communication unit 311. In Step S382, the CPU 301 in the shop-information portal site server 5 requests information on whether the article currently sold in the shop where the user is located is in stock (the information on whether the article currently sold is in stock is hereinafter referred to as stock information) from the stock management server 6 through the communication unit 311.

The stock management server 6 performs the process of providing the stock information shown in FIG. 23. Referring to FIG. 23, in Step S401, the CPU 351 in the stock management server 6 receives the request for the stock information transmitted by the shop-information portal site server 5 in Step S382 through the communication unit 361. At this time, the stock management server 6 stores the stock information of the article currently sold in the shop where the user is located in the HDD 354. In Step S402, the CPU 351 in the stock management server 6 reads out the stock information from the HDD 354 and transmits the readout stock information to the shop-information portal site server 5 through the communication unit 361.

Referring to back to FIG. 22, in Step S383, the CPU 301 in the shop-information portal site server 5 receives the stock information transmitted by the stock management server 6 in Step S402 through the communication unit 311. In Step S384, the CPU 301 in the shop-information portal site server 5 generates article information to be supplied to the base unit 2 based on the stock information received in Step S383. In Step S385, the CPU 301 in the shop-information portal site server 5 transmits the article information generated in Step S384 to the base unit 2 through the communication unit 311.

Referring back to FIG. 19, in Step S327, the CPU 201 in the base unit 2 receives the article information transmitted by the shop-information portal site server 5 in Step S385 through the wireless LAN communication unit 225 and stores the received article information in the HDD 223. In Step S328, the CPU 201 in the base unit 2 selects an article to be recommended to the user based on the user preference determined in Step S325 and the article information received in Step S327. In other words, the CPU 201 selects an article suited to the user preference from the list of articles that are included in the article information and that are sold in the shop where the user is located. The CPU 201 selects an article suited to the user preference based on, for example, whether a predetermined keyword (such as a user's favorite brand name) is associated with the article.

There is possibly no article suited to the user preference in Step S328. Accordingly, in Step S329, the CPU 201 determines whether the article to be recommended to the user is present in the processing in Step S328. If the article to be recommended to the user is present, the process proceeds to Step S330.

In Step S330, the CPU 201 in the base unit 2 transmits the information concerning the article (for example, the information concerning the price or characteristics of the article) selected in Step S328 to the remote unit 3 through the Bluetooth communication unit 221 and requests the remote unit 3 to recommend the article.

The remote unit 3 performs the process of presenting the information shown in FIG. 24. In Step S421, the CPU 151 in the remote unit 3 receives, through the Bluetooth communication unit 126, the information concerning the article and the request to recommend the article, transmitted by the base unit 2 in Step S330, and stores the received information and request in the RAM 153. In Step S422, the CPU 151 in the remote unit 3 presents the information concerning the article, received in Step S421. Specifically, for example, the CPU 151 vibrates the vibrators 124-1 and 124-2 and turns on the LED 159 or causes the LED 159 to blink. The CPU 151 then displays the information concerning the article (for example, an image, characteristics, and the price of the article) in the display 101. The CPU 151 also causes the speaker 105 through the audio output controller 158 to output a sound for guiding the article.

The user carrying the remote unit 3 in his/her hand takes notice of the remote unit 3 owing to the vibration of the vibrators 124-1 and 124-2. The user can browse the guide to the article suited to the user preference. The guide to the article includes a message displayed in the display 101 and an audio guide output from the speaker 105. The article recommended here is the article currently sold in the shop where the user is located.

Referring back to FIG. 19, if the CPU 201 in the base unit 2 determines in Step S329 that the article to be recommended to the user is not present in the processing in Step S328, the process proceeds to Step S331 in FIG. 20. In Step S331, the CPU 201 in the base unit 2 requests the remote unit 3, through the Bluetooth communication unit 221, to determine whether another article is to be recommended.

The remote unit 3 performs the process of confirming the recommendation shown in FIG. 25. In Step S441, the CPU 151 in the remote unit 3 receives the request to determine whether another article is to be recommended, transmitted by the base unit 2 in Step S331. In Step S442, the CPU 151 in remote unit 3 urges the user to determine whether another article is to be recommended. Specifically, the CPU 151 vibrates the vibrators 124-1 and 124-2 and turns on the LED 159 or causes the LED 159 to blink in order to call the user's attention to the remote unit 3. The CPU 151 then displays in the display 101 a message, such as “the shop has recommended clothes but it is out of stock. Would you like to look for clothes suiting you well?”.

A keyword used when another article is to be recommended (“look for” in the description below) and a keyword used when another article is not to be recommended (“stop” in the description below) are registered in the remote unit 3 in advance. When the user wants the recommendation of another article, the user speaks to the remote unit 3 the keyword “look for” used when another article is to be recommended. When the user does not want the recommendation of another article, the user speaks to the remote unit 3 the keyword “stop” used when another article is not to be recommended. The word the user speaks is collected by the microphone 102. The CPU 151 activates an audio recognition program to recognize the sound collected by the microphone 102. In Step S443, the CPU 151 in the remote unit 3 determines whether the word the user speaks coincides with the keyword “look for” as a result of the audio recognition. If the word the user speaks coincides with the keyword “look for”, the process proceeds to Step S444.

In Step S444, the CPU 151 in the remote unit 3 notifies the base unit 2 through the Bluetooth communication unit 126 that another article is to be recommended.

If the CPU 151 in the remote unit 3 determines in Step S443 that the word the user speaks does not coincide with the keyword “look for”, that is, if the CPU 151 determines that the word the user speaks is the keyword “stop” used when another article is not to be recommended or that the word the user speaks does not coincide with the keyword “look for” nor “stop”, the processing in Step S444 is skipped and the process of confirming the recommendation is finished. In this case, no information is transmitted to the base unit 2. The base unit 2 sets a timer for a predetermined time (for example, one minute) immediately after the base unit 2 requests the remote unit 3 to determine whether another article is to be recommended in Step S331. If no reply is transmitted from the remote unit 3 before the predetermined time the timer is set for elapsed, the base unit 2 determines that the remote unit 3 does not recommend another article and the process is finished.

With the timer set in this manner, even when the user does not aware of the urgency in Step S442, the base unit 2 need not continue to wait for the reply from the remote unit 3.

Referring back to FIG. 20, in Step S332, the CPU 201 in the base unit 2 receives the notification that another article is to be recommended, transmitted by the remote unit 3 in Step S444, through the Bluetooth communication unit 221. In Step S333, the CPU 201 in the base unit 2 determines a preference of the user based on the past shopping history stored in the HDD 223.

In Step S334, the CPU 201 in the base unit 2 requests the article information of the articles sold in another shop near the location of the user from the shop-information portal site server 5 through the wireless LAN communication unit 225.

The shop-information portal site server 5 performs the process of providing the article information shown in FIG. 22. Since the process of providing the article information in FIG. 22 is performed in the manner described above, the process is briefly described here. In Step S381, the CPU 301 in the shop-information portal site server 5 receives the request for the article information, transmitted by the CPU 201 in the base unit 2 in Step S334, through the communication unit 311. In Step S382, the CPU 301 in the shop-information portal site server 5 requests the stock information of the articles currently sold in the shop near the location of the user from the stock management server 6 through the communication unit 311.

The stock management server 6 performs the process of providing the stock information shown in FIG. 23. The process of providing the stock information in FIG. 23 is performed as described above. That is, in Step S401, the CPU 351 in the stock management server 6 receives the request for the stock information, transmitted by the shop-information portal site server 5 in Step S382, through the communication unit 361. In Step S402, the CPU 351 in the stock management server 6 reads out the stock information from the HDD 354 and transmits the readout stock information to the shop-information portal site server 5 through the communication unit 361. The stock information transmitted here is the stock information of the shop near the location of the user.

Referring back to FIG. 22, in Step S383, the CPU 301 in the shop-information portal site server 5 receives the stock information transmitted by the stock management server 6 in Step S402 through the communication unit 311. In Step S384, the CPU 301 in the shop-information portal site server 5 generates article information to be supplied to the base unit 2 based on the stock information. In Step S385, the CPU 301 in the shop-information portal site server 5 transmits the article information generated in Step S384 to the base unit 2 through the communication unit 311.

Referring back to FIG. 20, in Step S335, the CPU 201 in the base unit 2 receives the article information, transmitted by the shop-information portal site server 5 in Step S385, through the wireless LAN communication unit 225 and stores the received article information in the HDD 223. In Step S336, the CPU 201 in the base unit 2 selects an article to be recommended to the user based on the list, set in advance by the user, of the articles which the user wants to purchase, the user preference determined in Step S333, and the article information received in Step S335. In this selection (data mining), the CPU 201 in the base unit 2 selects, for example, the article that was recommended in a past similar situation or the article purchased by a person having a taste similar to that of the user, based on the past information detected by the sensors, data concerning the tendency in purchased articles, determined from the information concerning online shopping (online payment), and the information detected by the sensors when the service providing system is used for other purposes.

In Step S337, the CPU 201 in the base unit 2 requests the positional information of the shop where the article selected in Stet S336 is sold and routing information representing the route to the shop from the positional information service server 7 through the wireless LAN communication unit 225.

The positional information service server 7 performs the process of providing the routing information shown in FIG. 26. In Step S461, the CPU 401 in the positional information service server 7 receives the request for the positional information of the shop where the article is sold and the routing information representing the route to the shop, transmitted by the base unit 2 in Step S337, through the communication unit 411.

The HDD 404 in the positional information service server 7 stores multiple shops that are located in a predetermined area and the positional information associated with the multiple shops. In Step S462, the CPU 401 in the positional information service server 7 reads out the positional information of the shop where the article is sold from the HDD 404 in response to the request received in Step S461. In Step S463, the CPU 401 in the positional information service server 7 generates routing information for guiding the user to the shop based on the current position of the user and the positional information of the shop determined in Step S462.

In Step S464, the CPU 401 in the positional information service server 7 transmits the positional information determined in Step S462 and the routing information generated in Step S463 to the base unit 2 through the communication unit 411.

Referring back to FIG. 20, in Step S338, the CPU 201 in the base unit 2 receives the positional information and the routing information, transmitted by the positional information service server 7 in Step S464, through the wireless LAN communication unit 225 and stores the received positional information and routing information in the HDD 223. In Step S339, the CPU 201 in the base unit 2 transmits the positional information and the routing information, received in Step S338, to the remote unit 3 through the Bluetooth communication unit 221.

The remote unit 3 performs the route guiding process shown in FIG. 27. In Step S481, the CPU 151 in the remote unit 3 receives the positional information and the routing information, transmitted by the base unit 2 in Step S339, through the Bluetooth communication unit 126. In Step S482, the CPU 151 in the remote unit 3 stores the received positional information and routing information in the storage unit 154. The routing information includes the position (longitude and latitude) of a corner, which serves as a landmark for guiding the user to the shop. When the user reaches a corner, the CPU 151 uses the vibrators 124-1 and 124-2 or the like to present the destination based on the GPS information from the GPS detecting unit 125.

In Step S483, the CPU 151 in the remote unit 3 determines whether the user is located at a point where a guide is to be presented based on the routing information and the GPS information from the GPS detecting unit 125. The CPU 151 in the remote unit 3 repeats the processing in Step S483 until the CPU 151 determines that the user is located at a point where the guide is to be presented and is on standby. Since it is necessary to present the destination (direction of travel) to the user immediately after the CPU 151 stores the routing information in Step S482, the CPU 151 determines, in Step S483, whether the user is located at a point where the guide is to be presented immediately after the processing in Step S482, and the process proceeds to Step S484.

In Step S484, the CPU 151 in the remote unit 3 reads out a guide to be presented corresponding to the longitude and latitude in the GPS information from the routing information and presents the readout guide to the user. In other words, the routing information is information in which the longitude and latitude of a corner is associated with the direction of travel (right-hand turn or left-hand turn) of the user. When the user reaches a corner, the CPU 151 vibrates the vibrators 124-1 and 124-2 and turns on the LED 159 or causes the LED 159 to blink to attract the user's attention to the remote unit 3. The CPU 151 then displays a message (for example, a message “turn right”) in the display 101 or causes the speaker 105 through the audio output controller 158 to output an audio guide “turn right” to present the destination to the user.

In Step S485, the CPU 151 in the remote unit 3 determines whether the user reaches the target shop (the shop where the recommended article is sold) based on the GPS information and the positional information. If the user does not reach the target shop, the process goes back to Step S483 to repeat the steps subsequent to Step S483.

Repeating the steps from Step S483 to Step S485 ensures that the guide is presented to the user at the point where the user should turn. If the user reaches the target shop, the CPU 151 in the remote unit 3 determines in Step S485 that the user reaches the target shop, and the route guiding process is finished.

The article suited to the user preference can be presented to the user in the manner described above. Since the information concerning the shopping history or preference of the user is held and managed by the base unit 2, it is possible to reduce leakage of the private information of the user. Accordingly, compared with a case in which the private information including the shopping history or preference of the user is managed by a server on the network, the safety on the network can be improved.

Although the location of the user is determined based on the GPS information acquired by the GPS antenna 123 and the GPS detecting unit 125 of the remote unit 3 in the above description, the location of the user may be determined by other means, instead of the GPS information. For example, the location of the user may be determined by picking up an image of the logo or look of the shop by the imaging unit 121 in the remote unit 3 and analyzing the image. A detailed location of the user may be determined by using the rough location of the user determined based on the GPS information and the image picked up by the imaging unit 121.

Alternatively, the remote unit 3 may receive the ID identifying a shop to recognize the shop. In this case, the ID is transmitted by a low-speed communication module, such as an RF communication module, provided in the shop. In the case of a shop having an access point of a wireless LAN installed therein and providing a connection service (a so-called hotspot service) to the Internet, the ID identifying the shop may be transmitted from the access point of the wireless LAN to the remote unit 3. Or, a shop may be determined by picking up an image of a barcode tag, such as a CyberCode (trademark), provided in the shop by the imaging unit 121, analyzing the image, and recognizing the ID.

Furthermore, the location (station) of the user may be determined in conjunction with a super urban intelligent card (Suica), which is a non-contact type IC card.

When an article to be recommended to the user is clothes, images of clothes possessed by the user may be picked up by the imaging unit 121 and the preference of the user may be analyzed based on the images to select the article to be recommended to the user.

Although the vibration or turning on (blinking) of the remote unit 3 is used to guide the user to the shop (the route guiding process in FIG. 27) in the above description, a map may be displayed in the display 101, as in a car navigation system, to guide the user to the shop.

Next, a process of purchasing an article by the user will now be described with reference to the flowchart in FIG. 28. Since the remote unit 3 is provided with the IC communication unit 104, the remote unit 3 has a function as electronic money. When the user pays for an article in the shop through the IC communication unit 104, in Step S501, the CPU 151 in the remote unit 3 stores the article information, including the name and price of the purchased article, and the purchase information, including the purchase date and time, in the storage unit 154. In step S502, the CPU 151 in the remote unit 3 transmits the purchase information stored in the storage unit 154 in Step S501 to the base unit 2 through the Bluetooth communication unit 126.

In Step S511, the CPU 151 in the base unit 2 receives the purchase information transmitted by the remote unit 3 in Step S502 through the Bluetooth communication unit 221. In Step S512, the CPU 151 in the base unit 2 stores the purchase information received in Step S511 in the HDD 223.

The purchase information of the article purchased by the user is stored in the HDD 223 in the base unit 2 in the manner described above. The purchase information accumulated in the HDD 223 in this manner is used as shopping history information (the processing in Step S325 in FIG. 19 and the processing in Step S333 in FIG. 20).

Although the purchase information of the user can be acquired in the above description when the article is purchased through the IC communication unit 104, the purchase information cannot be acquired when the article is not purchased through the IC communication unit 104. Accordingly, in order to identify the article purchased by the user, the history of the articles purchased by the user may be acquired from, for example, a card company with which the user is affiliated in advance. Or, the article purchased by the user may be identified by reading the barcode or the like on the article. When the user inputs the information concerning a housekeeping book in the base unit 2, the information concerning the housekeeping book, input in the base unit 2, may be used to identify the article purchased by the user.

Although an article is recommended based on the position (GPS information) where the user is located in the above description, an article may be recommended to the user based on information other than the positional information according to the present invention.

Next, a case in which an article is recommended to the user based on audio information will now be described with reference to the flowcharts in FIGS. 29 to 32.

When the user speaks to the remote unit 3 about an article the user wants to buy, for example, when the user speaks a message “I want to buy a jacket matched with the pants I previously bought”, in Step S591 in FIG. 29, the microphone 102 in the remote unit 3 collects the sound. In step S592, the CPU 151 in the remote unit 3 transmits the audio information collected in Step S591 to the base unit 2 through the Bluetooth communication unit 126.

The base unit 2 starts a process of recommending an article based on the audio information, shown in FIGS. 30 and 31. In Step S601, the CPU 201 in the base unit 2 receives the audio information transmitted by the remote unit 3 in Stet S592 and stores the received audio information in the RAM 209. In Step S602, the CPU 201 in the base unit 2 activates an audio recognition program to analyze the audio information stored in the RAM 209 in Step S601. In Step S603, the CPU 201 in the base unit 2 stores the analysis result in Step S602 as an article the user wants to buy.

In Step S604, the CPU 201 in the base unit 2 requests the article information of the article the user wants to buy from the shop-information portal site server 5 through the wireless LAN communication unit 225. For example, when the user wants to buy a jacket, as described above, the CPU 201 in the base unit 2 requests the article information of jackets sold in the shop from the shop-information portal site server 5.

The shop-information portal site server 5 performs a process of providing the article information shown in FIG. 32. In Step S651, the CPU 301 in the shop-information portal site server 5 receives the request for the article information, transmitted by the base unit 2 in Step S604, through the communication unit 311. In Step S652, the CPU 301 in the shop-information portal site server 5 reads out only the article information of the article the user wants to buy (for example, the article information of the jackets) from among the article information stored in the HDD 304 and transmits the readout article information to the base unit 2 through the communication unit 311.

Referring back to FIG. 30, in Step S605, the CPU 201 in the base unit 2 receives the article information transmitted by the shop-information portal site server 5 in Step S652 through the wireless LAN communication unit 225. In Step S606, the CPU 201 in the base unit 2 selects an article to be recommended to the user based on the result of the audio analysis in Step S602 and the article information received in Step S605. For example, when the user wants to buy a jacket matched with the pants the user previously bought, as described above, the CPU 201 identifies the color of the pants the user previously bought based on the shopping history and selects a jacket having a color matched with the color of the pants based on the article information. In order to realize such selection, a table for coordinating colors is stored in advance in the HDD 223.

There is possibly no article the user can select in Step S606. Accordingly, in Step S607, the CPU 201 in the base unit 2 determines whether the article recommended in Step S606 is selected. If the recommended article is selected, the process proceeds to Step S608.

In Step S608, the CPU 201 in the base unit 2 transmits the information (for example, the information including the price and the characteristics of the article) concerning the article selected in Step S606 to the remote unit 3 through the Bluetooth communication unit 221 and requests the remote unit 3 to recommend the article.

The remote unit 3 performs the process of presenting the information shown in FIG. 24. Since the process in FIG. 24 is described above, the process is briefly described. In Step S421, the CPU 151 in the remote unit 3 receives the information concerning the article and the request to recommend the article, transmitted by the base unit 2 in step S608, through the Bluetooth communication unit 126 and stores the received information and request in the RAM 153. In Step S422, the CPU 151 in the remote unit 3 presents the information concerning the article, received in Step S421. A specific method of presenting the information is described above.

Referring back to FIG. 30, if the CPU 201 in the base unit 2 determines in Step S607 that the article to be recommended to the user is not present in Step S606, the process proceeds to Step S609. Since the steps from Step 609 to Step 617 are the same as the steps from Step 331 to S339 in FIG. 20, the description is omitted here.

An article can be recommended to the user based on the audio information in the manner described above. Although the article is recommended to the user based on the audio information in the above description, this does not mean that the present invention is limited to the recommendation of the article based on the audio information.

For example, as in a usual personal computer, the user may operate a keyboard or the like to input the request. The user may select a desired item from a list of menus (for example, “search”, “direction”, and “I want to read mails”), which are set in advance and which are displayed in the base unit 2 or the remote unit 3. The preference of the user may be analyzed based on the number of times the user browses Web pages. Alternatively, the history of the GPS information may be stored in the HDD 223 in the base unit 2 and the preference of the user may be analyzed based on the place (town or shop) the user frequently visits.

The service providing system of the present invention can present the information concerning an area where the user is located to the user. Specifically, for example, when the user gets on a train and gets off the train at a certain station, the service providing system of the present invention can present the information concerning events or bargain sales of articles around the station (in the town) to the user.

Next, a process of presenting the information concerning an area where the user is located to the user, that is, the area-information providing process will now be described with reference to the flowchart in FIG. 33. In Step S701, the CPU 151 in the remote unit 3 acquires the GPS information through the GPS detecting unit 125 and transmits the acquired information to the base unit 2 through the Bluetooth communication unit 126.

When the CPU 201 in the base unit 2 receives the GPS information transmitted by the remote unit 3 in Step S701 through the Bluetooth communication unit 221, in Step S711, the CPU 201 in the base unit 2 transmits the GPS information to the positional information service server 7 through the Wireless LAN communication unit 225 and requests the information concerning the area corresponding to the GPS information (longitude and latitude) (the information concerning an area is hereinafter referred to as area information).

In Step S721, the positional information service server 7 receives the GPS information and the request for the area information corresponding to the GPS information, transmitted by the base unit 2 in Step S711, through the communication unit 411. The positional information service server 7 associates the longitude and latitude with the area information and stores the associated information in the HDD 404. In Step S722, the CPU 401 in the positional information service server 7 reads out the area information corresponding to the GPS information, received in Step S721, from the HDD 404 and transmits the readout area information to the base unit 2 through the communication unit 411.

In Step S712, the CPU 201 in the base unit 2 receives the area information transmitted by the positional information service server 7 in Step S722 through the wireless LAN communication unit 225. In Step S713, the CPU 201 in the base unit 2 transmits the received area information to the remote unit 3 through the Bluetooth communication unit 221.

In Step S702, the CPU 151 in the remote unit 3 receives the area information transmitted by the base unit 2 in Step S713 through the Bluetooth communication unit 126. In Step S703, the CPU 151 in the remote unit 3 presents the area information to the user. Specifically, for example, the CPU 151 in the remote unit 3 vibrates the vibrators 124-1 and 124-2 and turns on the LED 159 or causes the LED 159 to blink to attract the user's attention to the remote unit 3. The CPU 151 in the remote unit 3 then displays the area information in the display 101 or causes the speaker 105 through the audio output controller 158 to output a guide to the area information.

The user can acquire the useful information concerning an area where the user visits for the first time owing to the guide to the area information.

The service providing system of the present invention can display different pictures corresponding to different positions in the display 101. The display of different pictures will be specifically described with reference to FIGS. 34 to 36. As shown in FIG. 34, a user 501 looks at the display 101 (not shown in FIG. 34) of the remote unit 3. The imaging unit 121 provided at a face opposing the display 101 picks up an image of a landscape within a certain angle. FIG. 35 shows an example of an image 511 picked up by the imaging unit 121. A predetermined image that is synthesized on the image 121 is displayed in the display 101. FIG. 36 shows an example in which a predetermined image that is synthesized on the image 511 in FIG. 35 is displayed in the display 101.

Referring to FIG. 36, a special picture 521 is generated by synthesizing synthesis images 522-1 to 522-4 on the image 511. Illustrations of a rocket, a balloon, and others are synthesized in FIG. 36. Although the illustrations are synthesized in FIG. 36, for example, descriptions (such as the origin of a temple) that are provided in sightseeing spots or the likes may be synthesized and displayed.

A process of synthesizing a synthesis image on a picked up image and displaying the synthesized picture in the display 101, that is, the special-picture providing process will now be described with reference to the flowchart in FIG. 37.

In Step S751, the remote unit 3 accepts an instruction to display a special picture, for example, through the operation unit 156. In Step S752, the CPU 151 in the remote unit 3 acquires the GPS information through the GPS detecting unit 125 to transmit the acquired GPS information to the base unit 2 through the Bluetooth communication unit 126 and to notify the base unit 2 that the instruction to display the special picture is input.

In Step S761, the CPU 201 in the base unit 2 receives the GPS information and the notification that the instruction to display the special picture is input, transmitted by the remote unit 3 in Step S752, through the Bluetooth communication unit 221. In Step S762, the CPU 201 in the base unit 2 transmits the GPS information received in Step S761 to the positional information service server 7 through the wireless LAN communication unit 225 and requests a synthesis image corresponding to the GPS information from the positional information service server 7.

In Step S771, the CPU 401 in the positional information service server 7 receives the GPS information and the request for a synthesis image corresponding to the GPS information, transmitted by the base unit 2 in Step S762. The positional information service server 7 associates the synthesis image with the GPS information and stores the associated image in the HDD 404. In Step S772, the CPU 401 in the positional information service server 7 reads out the synthesis image corresponding to the GPS information, received in Step S771, from the HDD 404 and transmits the readout synthesis image to the base unit 2 through the communication unit 411.

In Step S763, the CPU 201 in the base unit 2 receives the synthesis image transmitted by the positional information service server 7 in Step S772, through the wireless LAN communication unit 225. In Step S764, the CPU 201 in the base unit 2 transmits the synthesis image to the remote unit 3 through the Bluetooth communication unit 221.

In Step S753, the CPU 151 in the remote unit 3 receives the synthesis image transmitted by the base unit 2 in Step S764 through the Bluetooth communication unit 221 and stores the received synthesis image in the RAM 153. In Step S754, the CPU 151 in the remote unit 3 synthesizes the synthesis image stored in the RAM 153 in Step S753 on the picture (moving image or still image) picked up by the imaging unit 121 and displays the picture in the display 101.

The special-picture providing process is performed in the manner described above. Performing the special-picture providing process can improve the level of entertainment.

In Step S752, the CPU 151 in the remote unit 3 may transmit the image picked up by the imaging unit 121 to the base unit 2, in addition to the GPS information and the notification that the instruction to display the special picture is input, and may store the synthesis image in the RAM 153 along with image transmitted here.

As described above, according to the present invention, the user who carries the remote unit 3 having the sensors and the base unit 2 selecting information to be presented to the user can automatically perform the sensing in the base unit 2 and the remote unit 3, can detect the situation (problem) of the user, and can perform the problem solving, without operating the keyboard and/or mouse of a personal computer, unlike conventional cases.

Selecting information to be presented to the user in the base unit 2 can reduce the management cost in the server, compared with a case in which the server selects information to be presented to the user, and also can eliminate the time lag due to the communication with the server.

When the server selects information to be presented to the user as in conventional cases, it is necessary for all the relevant servers to properly operate. In contrast, according to the present invention, since the need for the server that selects information to be presented to the user is eliminated, the useful information can be stably provided to the user, independent of the operation state of the server.

The series of processes may be performed by hardware or by software. When the series of processes are performed by the software, the programs in the software are installed in a computer incorporated in dedicated hardware or in, for example, a general-purpose personal computer capable of performing various functions by installing various programs, over a network or from a recording media.

As shown in FIG. 7 and FIGS. 9 to 12, the recording media includes not only package media including the magnetic disk 241 (including a flexible disk), 321, 371, and 421; the optical disk 242 (including a compact disk read only memory (CD-ROM) and a digital versatile disk (DVD)), 322, 372, and 422; the magneto-optical disk 243 (including a minidisc (MD)), 323, 373, and 423; or semiconductor memory 244, 324, 374, and 424, which has the programs recorded therein and which is distributed for providing the programs to the user, independent of the main unit, but also the ROM 152, 302, 352, and the 402; the storage unit 154; and the HDD 223, 304, 354, and 404, which have the programs recorded therein and which are provided to the user in a state incorporated in the main unit.

In this description, the steps describing the programs recorded on the recording medium may be performed in the described order in time series or may be performed in parallel or individually.

In this description, a system represents the overall system including a plurality of apparatuses.
